ABSTRACT:
A varnishing apparatus for a printed sheet includes: a metering roller, to a peripheral surface of which a varnish from a varnish duct is transferred; a form roller which is brought into contact with a downstream side of the metering roller and is rotated in the same direction as that of the metering roller to allow transfer of the varnish from the metering roller; and a rubber blanket cylinder which is brought into contact with a downstream side of the form roller and is rotated in a direction opposite to that of the form roller to allow transfer of the varnish from the form roller, the rubber blanket cylinder having a notch on its outer peripheral portion and transferring the varnish onto a sheet which is in contact with its peripheral surface. The surface of the metering roller is formed of an elastic material having a roughened surface.
